Filed:

Oct 1, 1997

Appl. No.:

8/941987

Inventors:

David M Regen - Nashville TN

International Classification:

G10D 300

US Classification:

84318

Abstract:

A capo may be used on a guitar or banjo to reduce the operating length of all strings temporarily. The strings of a slide guitar (e. g. Dobro) are suspended approximately 1 cm above its fretboard and so cannot be clamped against a fret by a padded bar as with a Spanish guitar or banjo. In a typical embodiment, the slide-guitar capo is an essentially prismatic bar approximately 7-8 cm long, and made of metal or plastic. The three side faces of the prismatic bar are approximately 15. 2, 13. 7 and 12 mm wide; so that it has three ridge heights, approximately 10. 2, 11. 4 and 13 mm (were its edges not rounded) depending on which face is selected as base. A rectangular groove, 3. 5 mm wide and 1. 2 mm deep, runs the length of each side face of the bar, positioned below the bar's ridge when that face is the base. The side edges of the bar are rounded down approximately 0. 2 mm.

US Classification:

Abstract:

The invention is ammunition and ammunition components labeled so that either a projectile or a shell casing found at a crime scene can be associated with all documented handlers from the last documented recipient back to the manufacturer. The likely labeling code is a two-dimensional binary array with at least six cells (digits) in each dimension. Several different methods of imparting the label to a projectile at or near its rear end are described, some of which can be used in combination, including: adding a labeled identification member beneath the projectile's rear surface, embossing the projectile's rear surface, injecting pins through the projectile's rear end, embossing the projectile beneath the projectile's rear surface at a transition between metal layers of different melting temperatures, printing the projectile's rear surface with detectable material, etching the projectile's rear surface. Several different methods of imparting the label to the cylindrical wall of a shell casing are described, some of which can be used in combination, including: indenting from the outside to produce a braille-like symbol, printing on the outer surface with detectable material, printing on the inner surface with detectable material, etching on the outer surface, etching on the inner surface.

Abstract:

A house-wiring junction box having most conventional properties (compositions, shapes, dimensions, components, abilities) but being unconventional largely in that all side-wall cable ports may be opened both axially and radially by virtue of the box's reversible assembly from bottom and top partial boxes, the bottom partial box having the floor and lower parts of the side walls of the junction box, the top partial box having the upper parts of the side walls and the open top face of the junction box, the assembly seam intercepting all side-wall cable ports. Any side-wall cable port of the junction box may be unconventional in radial dimensions and in having an unconventional cable clamp, the base of which is built on to the bottom partial box continuous with the lower arc of the unconventional cable port, the shoe-and-shield element of which may be a knockout component of the top partial box, this element plugging the upper section of the unconventional cable port before it is removed for use in cable clamping, then shielding the same when used in cable clamping. Owing to these unconventional features, the junction box may be assembled about a connected branch junction or wired-up device and the cables thereof, the cables being clamped before or after this assembly.
